please help me ladies 🥺

so for years now i’ve been struggling with yeast infections i have one pretty much all the time, it never seems to go away either. i’ve been to the doctor for it once. i’ve also tried almost every type of monistat out there. i’m only 19 and i’m still not very educated on everything regarding vagina health. i seriously need some tips. do i bother making another appointment? is there a specific thing i should cut out of my diet? any type of pill i can get over the counter to help with the health and the ph balance of the vagina ? i’ll take any tips you guys have to help because i’m so frustrated lol.
